Motors need three things to start...spark, fuel and air.

Are your spark plugs getting spark?
Do you have adequate fuel pressure?

2000 mercury cougar will not start


If it is getting spark I will assume the timing belt is working.
You say the fuel pump is good, so what is the fuel pressure at the rail ?
Are the spark plugs wet or dry ? Can you get it to try to start by using starting fluid ?
You may have to get someone to check the computer for trouble codes which requires a scanner or code reader.

1998 Ford Escort starting problem after driven.


You did not say anything about the fuel system. Have you checked the fuel pressure ? Has the fuel filter been replaced this year ?
Is the check engine light on when the engine is running ?
Could be low fuel pressure or a faulty throttle position sensor among other things.

Engine will not run after cap, rotor, plugs and wires have been changed. distri hasn't been removed, but cam sensor also have been changed. All parts are new.


Has the fuel pressure been checked? How about the fuel filter? If fuel is good, this is likely going to be the CPS or crank position sensor which tells the computer when to fire number 1 and so on. Have you been able to scan for codes?

94 Honda Accord EX 2.2 YECH replaced head, now no fuel pump or fire to plugs. Pump works manually. distributor passes all test form manual . Replaced main relay and still have no power on blk/yel input...


Did you paint the spark-plugs? Not Good!
Run wire from negative to engine or from engine to the body.
You may have placed the timing onto the Exhaust stroke rather than the compression stroke if you moved the engine or you didn't have the timing set properly during assembly - perhaps to the wrong notch on the cam-shaft.
Always spin engine by hand several times with spark-plugs removed to ensure that nothing binds.
If you removed the oil pump = you may have to prime it as there may be a low oil-pressure cut-off!
Crank-shaft sensor is one other possibility?  
Bad Cam-sensor will only make it harder on fuel.
Best I can do for now.
Good luck.

Was running-stalled-turns over but will not fire.gas guage wont move and gas light stays on


check and make sure you have plenty of fuel in the tank. gas light should not be on as long you have plenty of fuel in the tank unless you have faulty fuel level sensor. check if you getting sparks and fuel, pull wire and one plug out, ground it to the vech have a friend turn over the engine and see if you getting strong sparks. no sparks check coil having 12V, good coil, cam sensor faulty. check if you getting fuel, pulling hose from the fuel filter line, point it down ward wrapping the end with clothes covering the hose and turn the engine over, see if you getting proper fuel and good pressure coming out of the line using your thumb slightly cover the fuel line. no pressure or fuel, check the fuel pump, good pump, faulty crank sensor. both crank and cam sensor work the same way, one telling computer to send sparks to the plugs and other turn on the fuel pump.

Audi 100s 1993 cranks doesn,t start, turns over no start. when it starts runs rough and stalls.


could very well be a faulty sensor, leaky vaccum hose, bad coil packs, needing of new fuel filter, spark plugs, wires.

Have you checked your fuel pressure to make sure it is good. You can do this with fuel pressure tester on the fuel rail.

Also check every cylinder for spark
If you don't have any spark, or very weak spark, you could have bad coil pack, module, or crank sensor.

You can remove one plug at a time, and place it back on plug wire, place it on top of engine block, have someone else turn motor over well you observe to see if there is spark.

Do you have a service or check engine light on? If so, I would have the engine codes read to pinpoint exact problem area.

Let me know if you have any questions or need further help

Do you know where or if a 2000 Mazda 626 has a fuel pump cut off switch. According to the parts store it doesn't have a fuel pump relay. I have replaced the fuel pump and the car still won't crank. I am...


Hello, I am going to make a few assumptions here. The vehicle has an electric fuel pump and you replaced it. The vehicle has fuel injection. The engine is actually cranking, just not starting, when you say "car still won't crank". You are getting fire to the spark plugs at the plug ends. You checked the fuel pump for power at the pump. No power, then you back traced the wire to the fuse block and checked the fuse to see if it was blown. If the fuse is good back trace the power to the ignition switch and/or ECM for power. You have power at the pump, check the ground and make sure it is connected properly. Will the pump run when someone turns the key on? Pump runs, check fuel manifold for pressure. No pressure, check the fuel filter for blockage, or replace it. Fuel pump doesn't run, new replacement pump is defective. There is usually some type of control module for the fuel pump on fuel injected vehicles. Good Luck, RAC

`i` have a 1998 jeep grand cherokee and it keeps backfiring and running like ****...I had a code po720 but changed the output sensor and the transmission sensor changed the throttle sensor and still same...


back firing ( explosions in the exhaust) can be from fuel mixture too rich and unburnt fuel is getting to the hot exhaust
possible causes for that are excessive fuel pressure , leaking injectors ,leaking injector seals
backfiring through the inlet manifold can be calve timing, ---cam advance servo-- valve staying open ---valve clearance , problem hydraulic cam follower , incorrect firing order for the plug wires, crank/cam position sensors or wiring
IN this country there is a joke about jeeps
Santa was late with the presents because he bought a jeep
